RFHA1020PCBA-410
型號:
RFHA1020PCBA-410
品牌:
QORVO/RFMD
產品分類:
RF放大器
描述:
詳細描述, ,The RFHA1020 is a 50V 280W high power discrete amplifier designed for L-Band pulsed radar, air traffic control and surveillance and general purpose broadband amplifier applications. Using an advanced high power density Gallium Nitride (GaN) semiconductor process, these high performance amplifiers achieve high output power, high efficiency, and flat gain over a broad frequency range in a single package. The RFHA1020 is a matched power transistor packaged in a hermetic, flanged ceramic package. The package provides excellent thermal stability through the use of advanced heat sink and power dissipation technologies. Ease of integration is accomplished through the incorporation of single, optimized matching networks that provide wideband gain and power performance in a single amplifier.,特點,Wideband Operation: 1.2GHz to 1.4GHz,Advanced GaN HEMT Technology,Advanced Heat-Sink Technology,Supports Multiple Pulse Conditions 10% to 20% Duty Cycle 100μs to 1ms Pulse Width,10% to 20% Duty Cycle,100μs to 1ms Pulse Width,Integrated Matching Components for High Terminal Impedances,50V Operation Typical Performance: Output Pulsed Power: 280W Pulse Width: 100μs, Duty Cycle 10% Small Signal Gain: 15dB High Efficiency (55%) - 40°C to 85°C Operating Temperature,Output Pulsed Power: 280W,Pulse Width: 100μs, Duty Cycle 10%,Small Signal Gain: 15dB,High Efficiency (55%),- 40°C to 85°C Operating Temperature
RF2059SR
型號:
RF2059SR
品牌:
QORVO/RFMD
產品分類:
射頻混合器
描述:
詳細描述,The RF2059 is a low power, high performance, wideband RF frequency conversion chip with integrated local oscillator (LO) generation and a pair of RF mixers. The RF synthesizer includes an integrated fractional-N phase locked loop with voltage controlled oscillator (VCO) and dividers to produce a low-phase noise LO signal with a very fine frequency resolution. The buffered LO output drives the built-in RF mixers which convert the signal into the required frequency band. The mixer bias current can be programmed dependent on the required performance and available supply current. The VCO has been designed to cover the frequency range from 1550 MHz to 2050 MHz. The LO dividers can be selected to divide the VCO output frequency by two or four to give lower LO frequencies. The RF mixers are very broad band and operate from 30 MHz to 2500 MHz at the input and output, enabling both up and down conversion. An external crystal of between 10 MHz and 52 MHz or an external reference source of between 10 MHz and 104 MHz can be used with the RF2059 to accommodate a variety of reference frequency options.,The high level of integration makes the RF2059 ideal for WLAN band shifting applications, offering a low cost and compact single chip solution.,All on-chip registers are controlled through a simple three-wire serial interface. The RF2059 is designed for 2.7 V to 3.6 V operation for compatibility with portable, battery powered devices. It is available in a plastic 32-pin, 5 mm x 5 mm QFN package.,特點,1550 MHz to 2050 MHz VCO? Frequency Range,30 MHz to 2.5 GHz Mixer?Frequency Range,Fractional-N Synthesizer,Low Phase Noise VCO,On-Chip Crystal-Sustaining Circuit With Programmable Loading Capacitors,Two High-Linearity RF Mixers,Integrated LO Buffers and Dividers,Mixer Input IP3 +18 dBm,Mixer Bias Adjustable for Low Power Operation,Full Duplex Mode,2.7 V to 3.6 V Power Supply,Low Current Consumption 55 mA to 75 mA at 3 V,3-Wire Serial Interface
